ICYMI, from Reuters:
"Democratic Senator Maria Cantwell on Tuesday said Verizon and AT&T are blocking release of key documents about an alleged massive Chinese spying operation that infiltrated U.S. telecommunications networks known as Salt Typhoon and wants their CEOs to appear before Congress to answer questions."
"Cantwell asked both companies to turn over security assessments conducted by Alphabet cybersecurity unit Mandiant. She said Mandiant refused to provide the requested network security assessments, apparently at the direction of AT&T and Verizon."
"In some cases, hackers are alleged to have intercepted conversations, including between prominent U.S. politicians and government officials. Several lawmakers have described them as the worst telecom hacks in U.S. history."
"Cantwell said Salt Typhoon allowed the Chinese government to "geolocate millions of individuals" and "record phone calls at will," and that the incident targeted almost every American."
